[Patch] unit test updates

[skyper]

Please, find attached patch file: josm_validator_numeric_unit_abb.patch​
which adds:

• adds test about long forms of common units and autofixes them to abbreviations: m, ft and t
• combines the test for separator and the general warning to one for each group instead of one for each tag
• adds maxaxleload and maxlength to the tests

I was wondering why the regex for width differs compared to the other tags but did not change it, so far:

*[width][width !~ /^(([0-9]+\.?[0-9]*( [a-z]+)?)|([0-9]+\'([0-9]+\.?[0-9]*\")?))$/]

instead of:

*[width][width !~ /^(([0-9]+\.?[0-9]*( (m|ft))?)|([0-9]+\'[0-9]+\.?[0-9]*\"))$/]
